The Iomega SuperHero is a charger and backup station for the iPhone and iPod Touch.

One of the unsung accessories at this year's CES might be the Iomega SuperHero, a device that lets you charge and back up your iPhone with an SD card. It looks like a simple docking station, but on the back is an SD card slot that you can use to back up your contacts and photos.

As the capacity is limited to 4GB, it's obviously not meant for your music or video collection, and it's not meant as a replacement for iTunes. The idea behind it is that some people don't hook up their phones to the computer that often, and the Iomega SuperHero is an easy way for them to still back up those all-important contacts and photos.

Simply dock the device, and the backup will be done automatically. It will work with the latest-generation iPod Touch, and it might also be useful if you're switching to another iPhone.

You do need to download the free SuperHero iPhone Backup App from the App Store to back up and restore the phone. The charger itself is $70, and is available now.
